Exporting GLTF with mutliple clips workaround? 2025年5月2日14:07
Hi, I know that Houdini's GLTF support isn't as robust as Blender -- for example, a GLTF can only have one animation clip instead of several which makes it pretty onerous to deliver multiple animations for a character (each GLTF now has redundant mesh and skeleton data).
Has anybody come up with a workaround for this? I don't really want to add Blender to the mix, especially if this is an operation I can do post-export by calling a command line script. I am somewhat familiar with GLTF-Transform for mesh compression but I'm not sure if that can collate my animation clips for me, or if there is a better option out there.
Would love to learn what people are doing (besides switching to Blender for GLTF export).

[APEX Animate Scene SOP] Hide Controllers When Flipbooking? 2025年4月15日1:34
Is there a way to have the "Hide Controllers During Playback" setting apply to flipbooks as well? I had assumed "Hide Controls During Playback" would also hide controls during flipbook generation since it is technically playing back, albeit slowly.
Exporting vertex color and vertex alpha via GLTF? 2025年4月12日20:28
Quick follow-up question, I found this GLTF exporter code in the sideffects repo here:
https://github.com/sideeffects/HoudiniGLTF/blob/Houdini18.5/src/ROP/ROP_GLTF_Refiner.C [github.com]
Is this accurate to what is currently in Houdini? The description says this repo contains the source for the GLTF exoprter code but it also hasn't been updated in five years, so it seems like it is abandoned? Just wondering if I could hunt around the C code in lieu of documentation.

else if (attrib_name == GA_Names::Cd)
{
uint32 vertex_colors = AddAttrib(attrib_data, GLTF_COMPONENT_FLOAT, 3,
0, GLTF_BUFFER_ARRAY);
prim.attributes.insert({"COLOR_0", vertex_colors});
}
